Can I use the schedule() function to suspend my driver to allow a user-space process to
run? I have an application that simulates my hardware, and it runs with 100% CPU. It
polls on a memory buffer to see if the driver has written any data to this. Yes, it's
inefficient, but it has the advantage of completely de-coupling the driver from the simulator.
Sometimes the driver needs to pause to allow the simulator to run. Can I use the
schedule() function for this? If I call schedule() in my driver, what can I do to make
sure that my user process runs before schedule() returns?
